Most kangaroos are 'left-handed' - BBC News

Wild kangaroos tend to favour their left hands during common tasks like grooming and feeding, a study suggests.
The researchers say this is the first demonstration of population-level "handedness" in a species other than humans, who are mostly right-handed.
The evidence comes from hours spent observing multiple species in the wild.
Two species of roo and one wallaby all showed the left-handed trend; some other marsupials, which walk on all fours, did not show the same bias.


Similarly, they suggest, the transition to an upright posture may have been key to primates developing handedness.
It remains to be seen if there are particular aspects of the brain in these marsupials that have allowed handedness to develop - and whether they can explain why kangaroos, in contrast to predominantly right-handed humans, tend to be southpaws.

key to primates developing handedness.

ape to kangaroo,................etc to humans, do you think science is sending confusing signs to the next generation. what are they teaching in school these days. in contrast to predominantly right-handed humans, tend to be southpaws.

That's because they live south of the equator. You know the toilet bowl effect.

Evolution is a load of bollocks, but this is nonetheless quite interesting. Especially since I belong to the left-hander's club.

And why was tax money spent on this?
How can people accept a pay check for doing this kind of research when children are dying of hungar every day?

I've always felt like there was something really strange about left handed people...
not it's obvious that they're actually kangaroos.

Funny....I have been to Australia 4 times in the last 8 months and fixing to go again and I don't recall which way the "loo" flushes, but I will say....they definitely have the toilet figured out down under........!

How do you even tell if a kangaroo is left handed?

You hand him a pen and paper and see which way he writes a letter?

(For the really young people, a pen is this thing we used to write with. It's full of ink inside. Oh, and ink is this stuff that's like paint, but thinner, and it would come out of the pen and go onto the paper. Oh, and paper is this stuff that... ya know, this is a way harder than I expected.)
